Netflix highquality audio makes TV shows and films sounds better

first_img Comments High-quality audio not only delivers a higher bit rate but can adapt to the speed of your internet connection by increasing or decreasing that bit rate. Netflix video already does something similar. If you’ve ever been on a slower connection, you have probably seen video playback at a lower quality until there’s enough of a buffer for it to switch to a higher quality version. High-quality audio will do the same and move up and down in quality seamlessly as you watch a show.Currently high-quality audio is rolling out to TVs and connected boxes with support for 5.1 or Dolby Atmos. Devices with 5.1 will receive a bit rate of 192 to 640 kilobits per second. If you’re a Premium Netflix subscriber and have an Atmos device, playback will be between 448 and 768 kbps. Tags Netflix teases Stranger Things season 3 in new trailer Netflix I had a chance to experience the new high-quality audio listening to a sequence from Stranger Things. There were three versions: the original master, a low bit rate one (192 kbps) and a higher bit rate one (640 kbps). The low bit rate version sounded fine, but when compared to the original master it lacked subtle audio details and clarity. The high bit rate version, to my ears, was identical to the original master achieving a phenomena called “perceptually transparent” — don’t worry, I didn’t know what that meant at first either.Perceptually transparent — which, by the way, would be a great name for an improv group — means there are no perceived differences between a studio master and audio that has been compressed. For Netflix streaming that perceptually transparent sweet spot was 640 kbps.Netflix said that these bit rates might “evolve” over time as the company gets more efficient with its encoding.

The streaming company has released a new feature called high-quality audio that makes sure what you hear is closer to what the artists behind your favorite show intended. Netflix’s improved audio came about because of the show Stranger Things’ second season.The first episode of Stranger Things season 2 starts off with a car chase. But when the Duffer brothers, the show’s creators, first heard it played back in a living room, they noticed that the sound wasn’t as crisp as the original master from the studio.”It didn’t sound quite as defined. A little bit mushy, you might say. Or like maybe there’s a napkin over it,” said Scott Kramer, manager of sound technology for Netflix. “Very subtle, but noticeable.”To address the issue, the show was streamed at a higher bit rate that sounded closer to the original studio master. This laid the groundwork for Netflix to create its new high-quality audio feature. TV and Movies Audio Now playing: Watch this: 2:50 Share your voice 24last_img read more

How Texas Could Monitor Students Social Media Posts More Closely

first_img Share Listen AP Photo/Eric GaySanta Fe students takes part in a roundtable discussion in Austin, Texas, Thursday, May 24, 2018, hosted by Texas Gov. Gregg Abbott to address safety and security at Texas schools in the wake of the shooting at Santa Fe, Texas.Law enforcement plans to watch students’ social media more closely after the Santa Fe High School shooting, since Governor Greg Abbott wants to use technology to find threats online as part of his school safety plan. X 00:00 /00:52center_img In his plan released last week, Abbott wants people to use a new state developed app, called iWatch. It will be launched this month by the Texas Department of Public Safety. It lets people report suspicious behavior and then alerts law enforcement.However, some schools already monitor what students say on social media. The Spring Independent School District uses a program called Social Sentinel and Katy ISD recently decided to it as well.The technology scans for threatening words online and sends alerts to district officials. Spring’s spokeswoman Karen Garrison said in an email that the district also plans to use funds from its recent $330 million bond package to upgrade its surveillance camera system.But David McGeary with the Harris County Department of Education told News 88.7 an old fashioned approach could be more effective in “curbing behaviors that can lead to violent outbursts or that can lead to critical events.”And those, he said, are still largely face-to-face rather than social, so building positive relationships inside of the school could mitigate risk more than anonymous reporting apps or social media scanning.“To look at it as sort of  a panacea to school violence, or bullying or students at risk of suicide is kind of short-sighted. I think you do have to sort of take this multi-paneled approach to mitigating risk, but that starts with relationships in the schools and you build technology to layer on top of everything else,” McGeary said.That’s why many students and educators want to see more counselors in schools, something that Texas law doesn’t require.
